These charred pieces of paper from a maths textbook are all that remain of one of the 75 houses incinerated by the fire

In Northern California, the record-breaking Mendocino Complex twin fires grew at a slower rate yesterday, according to the California Department of Forestry.

The flames, which have burned 457-square-miles of land, broke out on July 27 and spread quickly due to a "perfect combination" of weather, abundant brush and timber turned to tinder by years of drought.

Resources were thin at first because thousands of firefighters already were battling another fire hundreds of miles north.

The so-called Carr Fire, which spread into the city of Redding, killed six people and destroyed more than 1,000 homes.

"Since civilisation emerged 10,000 years ago, we haven't had this kind of heat condition, and it's going to continue getting worse. That's the way it is."
